Certainly! Here is the transcribed content as it would appear on an educational website: --- **Problem Analysis and Graphical Representation of a Function** Consider the function \( f(x) = x^4 + 2x^3 - 1 \), whose only zeros are \( x \approx -2.1 \) and \( x \approx 0.7 \). **Tasks:** a. **Find the critical points of \( f(x) \).** b. **Indicate where the function \( f(x) \) is increasing or decreasing.** c. **Classify the local extreme values (max or min).** d. **Indicate where the function \( f(x) \) is concave up or concave down.** e. **Find all inflection points.** f. **Give a rough sketch of the graph of \( f(x) \) indicating all of these features.** --- For further exploration, detailed explanations, and solutions, consider utilizing calculus techniques such as deriving the first and second derivatives to determine these features accurately.
